I am on SL 10.6.3 retail install, on a HP dv9 laptop with 2,4 Ghz Core 2 Duo, chameleon 2.0 RC4.I have a custom DSDT file (parts about speedstepping never edited though)and an edited smbios.plist to look like macbookpro3,1. (don't know if that matters)

When I use voodoopowermini.kext 1.2.7, speedstepping seems to work well, (and no errors while loading)except that it never goes to the fastest step of 2392 Mhz. When I stress the CPU (benchmark software or just rendering in final cut pro) it does a constant 2208Mhz, which is the second highest Pstate. Also it seems to change steps a bit slowly (seems to rather stick to 552Mhz idle speed, only goes 2208 if I stress it for longer times). But that is less important, I would just really like it to go 2392Mhz while rendering.

I use the kext in /Extra/Extensions, putting it in /S/L/E it behaves the same.Using debug version it also behaves exacly the same.I tried putting other things in smbios but it makes no difference at all, just wrongly displayed bus speed.

Since I couldn't seem to upload any attachments, I have written down my pstates as in voodoomonitorand part of my kernel log with voodoopower messages (from debug version).Thank you very, VERY much for having a look...Cheers
